Behold, cretins! It is I, Kang the Conqueror! Today, I bring forth to you an opportunity to purchase the most deadly of allies: the ninja!
Freshly plucked from 16th century feudal Japan (courtesy of my seemingly endless brilliance in regards to time travel,) these warriors are adept at stealthy assassinations and espianoge, plus they come complete with katanas, shuriken, and other such nonsense they happen to be carrying at the time of their abduction. I mean aquisition.
No personal checks!
